COLLADA is a COLLAborative Design Activity for establishing an open standard digital asset schema for interactive 3D applications. It involves designers, developers, and interested parties from within Sony Computer Entertainment America (SCEA) as well as key third-party companies in the 3-D industry. With its 1.4.0 release, COLLADA became a standard of The Khronos Group Inc., where consortium members continue to promote COLLADA to be the centerpiece of digital-asset toolchains used by the 3-D interactive industry.
COLLADA™ defines an XML-based schema to make it easy to transport 3D assets between applications - enabling diverse 3D authoring and content processing tools to be combined into a production pipeline. The intermediate language provides comprehensive encoding of visual scenes including: geometry, shaders and effects, physics, animation, kinematics, and even multiple version representations of the same asset.COLLADA FX enables leading 3D authoring tools to work effectively together to create shader and effects applications and assets to be authored and packaged using OpenGL® Shading Language, Cg, CgFX, and DirectX® FX.
glTF - runtime asset format for WebGL, OpenGL ES, and OpenGL
The "glTF" project aims to define a final stage OpenGL Transmission Format to enable rapid delivery and loading of 3D content by WebGL, OpenGL, and OpenGL ES APIs. glTF together with COLLADA comprise a standards-based content pipeline for rich 3D web and mobile applications. glTF Specification is a work-in-progress from the COLLADA Working Group; it is not an official Khronos-ratified specification yet. It is incomplete and subject to change. The draft specification and related converters and loaders are available on github.
COLLADAMax and COLLADAMaya are new implementation of a 3ds Max or Maya plug-ins to export scene or parts of it to a COLLADA file, released under an MIT-license. In contrast to other existing COLLADA exporters, these new plug-ins do not store the COLLADA document in an intermediate data model but writes it directly to file. This leads to a dramatic reduction of memory consumption and to much better performance.
The COLLADA intermediate language specification is intended to standardize 3D data, but there’s a wide variation in the way applications work with COLLADA files. To help developers adhere to the standard and create 3D tools that work together seamlessly, the Khronos Group created the COLLADA Conformance Test Suite (CTS).
Information about products that provide COLLADA plug-ins or that import or export COLLADA. This information is submitted by various vendors and users. To assure that implementations of Khronos specifications meet a consistent standard of the highest quality, the Khronos Group maintains Adopter Programs that provide access to conformance tests for verification by Khronos that a product or implementation conforms to the specification. To find out how you can use the COLLADA trademark (in text or logo form) in association with your product please visit Khronos Adoption and Conformance Testing.
The COLLADA extensions directory is where vendors may follow the official COLLADA Extensions Process, to publish their extensions. These extensions are based on the COLLADA extensibility mechanisms that involve the use of the following elements: <extra>, <technique>, and <input>. Parametrization of effects is left out of this definition.
The COLLADA Document Object Model (DOM) is a C++ library for loading and saving COLLADA data. The latest official release of the DOM is version 2.2, which is available as a download on Sourceforge.
COLLADA Coherency Test
COLLADA Coherency Test is a command-line version of CoherencyTest from COLLADA Refinery. It checks whether a COLLADA dae file is coherent (properly composed). It is built using the COLLADA DOM library on Sourceforge. It is developed in C/C++ and built using MSVC.

Cesium uses the web-friendly glTF format for 3D models. Cesium provides an online COLLADA-to-glTF converter that allows us to drag and drop a COLLADA model and its textures to produce a glTF model for use in Cesium. This blog post is a series of tips for authoring 3D models and then exporting them to COLLADA to get the best performance and robustness. Read More
The Khronos Group will be at SIGGRAPH Asia this coming weekend. Neil Trevett, Khronos Group President and VP of Mobile Content at NVIDIA will be speaking. There will be a panel session "Next Frontiers For Interactive Applications" on Saturday followed by a tech-talk "What's Next In Graphics APIs?" on Saturday December 6th which will cover the rapidly changing landscape of acceleration APIs for mobile devices and the Next Generation OpenGL Initiative first revealed at SIGGRAPH 2014.
